    LA TRANSPIRACION DE LAS PLANTAS ES UNO DE LOS PRINCIPALES COMPONENTES DEL CICLO DEL AGUA GLOBAL, Y AL MISMO TIEMPO, LA DISPONIBILIDAD DE AGUA ES UNO DE LOS PRINCIPALES FACTORES ABIOTICOS QUE LIMITAN LA PRODUCTIVIDAD, EL CRECIMIENTO Y LA SUPERVIVENCIA DE LAS PLANTAS. EL INCREMENTO DE LAS TEMPERATURAS, JUNTO CON CAMBIOS EN LOS PATRONES DE PRECIPITACION DEBIDOS AL CALENTAMIENTO GLOBAL, YA ESTAN CAUSANDO EXTENSOS EFECTOS NEGATIVOS EN LA VEGETACION MUNDIAL, ESPECIALMENTE EN LOS BOSQUES. EL DECAIMIENTO FORESTAL INDUCIDO POR LA SEQUIA SE ESTA DOCUMENTANDO CADA VEZ MAS A ESCALA GLOBAL Y ESTA AMENAZANDO LOS SERVICIOS ECOSISTEMICOS QUE PROPORCIONAN LOS BOSQUES, TALES COMO LA REGULACION CLIMATICA, EL BALANCE HIDRICO LOCAL Y EL SECUESTRO DE CARBONO. POR TANTO, ENTENDER LOS PRINCIPALES AMBIENTALES EN EL USO DEL AGUA DE LOS ARBOLES Y SU VULNERABILIDAD A LA SEQUIA ES ESENCIAL PARA TRATAR LAS CUESTIONES RELEVANTES AL INCREMENTO DE LA SEQUIA DEBIDO AL CAMBIO GLOBAL._x000D_ ESTUDIOS GLOBALES DE LOS RASGOS QUE CONFIEREN TOLERANCIA A LA SEQUIA AL NIVEL DE ORGANO (HOJAS, TALLOS, RAICES) ESTAN INCREMENTANDO NUESTRO CONOCIMIENTO DE LA DIVERSIDAD DE ESTRATEGIAS FUNCIONALES FRENTE A LA SEQUIA. SIN EMBARGO, UN ESTUDIO GLOBAL Y EXHAUSTIVO DE LOS FACTORES QUE CONTROLAN LA TRANSPIRACION A NIVEL DE ARBOL, CONTRIBUIRIA CON UNA PERSPECTIVA A NIVEL DE ORGANISMO AL ESPECTRO DE RASGOS HIDRAULICOS DE LAS PLANTAS Y MEJORARIA NUESTRO CONOCIMIENTO DE LOS EFECTOS DE LA SEQUIA EN LOS MONTES. LAS MEDIDAS DE FLUJO DE SAVIA BASADAS EN METODOS TERMICOS SE HAN APLICADO PARA MEDIR PATRONES ESTACIONALES DEL USO DEL AGUA Y LA RESPUESTA DE LA TRANSPIRACION A LOS FACTORES AMBIENTALES EN CIENTOS DE ESPECIES LEÑOSAS, BAJO UN AMPLIO RANGO DE CONDICIONES CLIMATICAS, DE SUELO Y DE ESTRUCTURA DE LA VEGETACION. EN ESTE PROYECTO, COMPILAREMOS UNA BASE DE DATOS GLOBAL DE FLUJO DE SAVIA SUB-DIARIO, MEDIDO A ESCALA DE ARBOL (SAPFLUXNET), QUE SERVIRA PARA MEJORAR NUESTRO CONOCIMIENTO DE LOS DETERMINANTES ESTRUCTURALES Y FISIOLOGICOS DE LA TRANSPIRACION DE LAS PLANTAS Y PARA INVESTIGAR EL PAPEL DE LA VEGETACION EN EL CONTROL DEL CICLO DEL AGUA GLOBAL. ANALIZAREMOS COLECTIVAMENTE RESPUESTAS DEL FLUJO DE SAVIA A LOS FACTORES AMBIENTALES, A ESCALAS TEMPORALES QUE ABARCAN DE LA DIARIA A LA ESTACIONAL Y ANUAL. PARA ELLO UTILIZAREMOS MODELOS ESTADISTICOS, ANALISIS DE SERIES TEMPORALES Y MODELIZACION MECANICISTA DEL TRANSPORTE DE AGUA EN PLANTAS. ESTOS ANALISIS RESULTARAN EN UN CONJUNTO DE RASGOS RELACIONADOS CON LA REGULACION FISIOLOGICA DE LA TRANSPIRACION PARA CADA ESPECIE. ESTOS RASGOS SE ANALIZARAN EN SU CONTEXTO ECOLOGICO, INCLUYENDO GRUPOS TAXONOMICOS, TIPOS DE ANATOMIA DE LA MADERA, VARIABLES CLIMATICAS Y DE SUELO Y TAMAÑO DEL ARBOL Y ESTRUCTURA DE LA VEGETACION. POSTULAMOS QUE ESTOS RASGOS INDICATIVOS DE LA REGULACION FISIOLOGICA DE LA TRANSPIRACION JUEGAN UN PAPEL CENTRAL EN LA DEFINICION DE ESTRATEGIAS PARA AFRONTAR LA SEQUIA A ESCALA DE PLANTA Y QUE, POR TANTO, ESTARAN COORDINADOS CON OTROS RASGOS HIDRAULICOS A NIVEL DE PLANTA Y ORGANO._x000D_ SAPFLUXNET ES UNA APROXIMACION GLOBAL Y NOVEDOSA AL ESTUDIO DE LOS FACTORES ECOLOGICOS QUE CONTROLAN LA TRANSPIRACION A NIVEL DE INDIVIDUO, LA ESCALA RELEVANTE PARA TRATAR LAS RESPUESTAS DE LAS PLANTAS AL CAMBIO GLOBAL Y A LOS EVENTOS CLIMATICOS EXTREMOS. SAPFLUXNET TENDERA PUENTES ENTRE LAS ESCALAS ECOLOGICAS EN LAS BASES DE DATOS GLOBALES DE RASGOS FUNCIONALES DE LAS PLANTAS Y LAS REDES DE MEDIDA DE FLUJOS DE AGUA Y CO2 A NIVEL DE ECOSISTEMA.

    PERSPIRATION OF PLANTS IS ONE OF THE MAIN COMPONENTS OF THE GLOBAL WATER CYCLE, AND AT THE SAME TIME, WATER AVAILABILITY IS ONE OF THE MAIN ABIOTIC FACTORS THAT LIMIT PLANT PRODUCTIVITY, GROWTH AND SURVIVAL. RISING TEMPERATURES, ALONG WITH CHANGES IN PRECIPITATION PATTERNS DUE TO GLOBAL WARMING, ARE ALREADY CAUSING WIDESPREAD NEGATIVE EFFECTS ON GLOBAL VEGETATION, ESPECIALLY IN FORESTS. DROUGHT-INDUCED FOREST DECLINE IS INCREASINGLY BEING DOCUMENTED ON A GLOBAL SCALE AND IS THREATENING THE ECOSYSTEM SERVICES PROVIDED BY FORESTS, SUCH AS CLIMATE REGULATION, LOCAL WATER BALANCE AND CARBON SEQUESTRATION. For the first time, to understand the primary environment in the use of the water of the arms and their vulnerability to the drying up is essential to treat the questions raised by the dryness due to the GLOBAL CHANGE._x000D_ GLOBAL STUDIES OF RASGS that CONFERENCE TO THE SEQUIA to the LEVEL OF ORGANO (JOJAS, TALLOS, RAICES) They are increasing our knowledge of the diVERSITY of FUNCIONAL STRATEGIES FENT to the dry. HOWEVER, A COMPREHENSIVE AND COMPREHENSIVE STUDY OF THE FACTORS THAT CONTROL PERSPIRATION AT THE TREE LEVEL WOULD CONTRIBUTE WITH AN ORGANISM-LEVEL PERSPECTIVE TO THE SPECTRUM OF HYDRAULIC TRAITS OF PLANTS AND WOULD IMPROVE OUR KNOWLEDGE OF THE EFFECTS OF DRYNESS ON THE MOUNTAINS. SAP FLOW MEASURES BASED ON THERMAL METHODS HAVE BEEN APPLIED TO MEASURE SEASONAL PATTERNS OF WATER USE AND THE RESPONSE OF PERSPIRATION TO ENVIRONMENTAL FACTORS IN HUNDREDS OF WOODY SPECIES, UNDER A WIDE RANGE OF CLIMATIC, SOIL AND VEGETATION STRUCTURE CONDITIONS. IN THIS PROJECT, WE WILL COMPILE A GLOBAL DATABASE OF SUB-DAILY SAP FLOW, MEASURED AT TREE SCALE (SAPFLUXNET), THAT WILL SERVE TO IMPROVE OUR KNOWLEDGE OF THE STRUCTURAL AND PHYSIOLOGICAL DETERMINANTS OF PERSPIRATION OF PLANTS AND TO INVESTIGATE THE ROLE OF VEGETATION IN THE CONTROL OF THE GLOBAL WATER CYCLE. WE WILL COLLECTIVELY ANALYSE SAP FLOW RESPONSES TO ENVIRONMENTAL FACTORS, AT TIME SCALES RANGING FROM DAILY TO SEASONAL AND ANNUAL. FOR THIS WE WILL USE STATISTICAL MODELS, ANALYSIS OF TIME SERIES AND MECHANICAL MODELLING OF WATER TRANSPORT IN PLANTS. THESE ANALYSES WILL RESULT IN A SET OF TRAITS RELATED TO THE PHYSIOLOGICAL REGULATION OF PERSPIRATION FOR EACH SPECIES. THESE TRAITS WILL BE ANALYSED IN THEIR ECOLOGICAL CONTEXT, INCLUDING TAXONOMIC GROUPS, TYPES OF WOOD ATOMIA, CLIMATIC AND SOIL VARIABLES AND TREE SIZE AND VEGETATION STRUCTURE. We postulate THIS INDICATIVE RASGS OF THE PHYSIOLOGICAL REGULATION OF PREPEANCE PLAY A CENTRAL PEOPLE IN THE DEFINICATION OF STRATEGICS TO AFRON THE WITCH TO THE SCHOOL OF PLANTA AND THAT, BY QUE, BEFORE, COORDINED WITH OTHER HIDRAULIC RAGOS TO LEVEL OF PLANTA AND ORGANO._x000D_ SAPFLUXNET is a GLOBAL and NEW approximation to the state of the ECOLOGICAL FACTORS that control the perspiration to INDIVIDUUS LEVEL, THE RELEVANT ESCAL to treat the answers of the PLANTS to the GLOBAL CHANGE and EXTREMAL CLIMATIC EVENTS. SAPFLUXNET BRIDGES BETWEEN ECOLOGICAL SCALES IN GLOBAL PLANT FUNCTIONAL TRAITS DATABASES AND WATER AND CO2 FLOW MEASUREMENT NETWORKS AT ECOSYSTEM LEVEL. (English)
